Left atrium segmentation for atrial fibrillation ablation
Segmentation of the left atrium is vital for pre-operative assessment of its anatomy in radio-frequency catheter ablation (RFCA) surgery. RFCA is commonly used for treating atrial fibrillation. In this paper we present an semi-automatic approach for segmenting the left atrium and the pulmonary veins from MR angiography (MRA) data sets. We also present an automatic approach for further subdividi...
متن کاملAcute effects of left atrial radiofrequency ablation on atrial fibrillation.
INTRODUCTION Acutely, when left atrial ablation is performed during atrial fibrillation (AF), the AF may persist and require cardioversion, or it may convert to sinus rhythm or to atrial tachycardia/flutter. The prevalence of these acute outcomes has not been described. METHODS AND RESULTS Left atrial ablation, usually including encirclement of the pulmonary veins, was performed during AF in ...
متن کاملradiofrequency atrial fibrillation ablation technique in patients with mitral valve surgery and left atrial reduction procedures
background: about half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (af). cox described the surgical cut-and-sew maze procedure, which is an effective surgical method but has some complications. this study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (rfa) for patients undergoing mitral valve surgery with af. metho...
متن کاملMidterm results of left atrial bipolar radiofrequency ablation combined with a mitral valve procedure in persistent atrial fibrillation
INTRODUCTION The aim of the study was to assess the midterm results of left atrial bipolar radiofrequency ablation combined with a mitral valve procedure in patients with mitral valve disease and persistent atrial fibrillation. METHODS Between October 2006 and July 2009, 95 patients with mitral valve disease and persistent atrial fibrillation underwent a mitral valve procedure and left atrial...
متن کاملSpecific linear left atrial lesions in atrial fibrillation: intraoperative radiofrequency ablation using minimally invasive surgical techniques.
OBJECTIVES A specific left atrial (LA) linear lesion concept for treatment of paroxysmal and permanent atrial fibrillation (AF) was tested using intraoperative ablation with minimally invasive surgical techniques. BACKGROUND Curative treatment for patients with chronic AF is among the main challenges of interventional electrophysiology. METHODS Seventy patients (mean age 53 +/- 10 years) wi...
